manufactured for safe operation In order to ensure safe operation, it is very important that this manual be read in its entirety prior to installing or operating the pump Flowserve shall not be liable for physical injury, damage or delays caused by a failure to observe the instructions for installation, operation and maintenance contained in this manual Remember that every pump has the potential to be dangerous, because of the following factors: • parts are rotating at high speeds • high pressures may be present • high temperatures may be present • highly corrosive and/or toxic chemicals may be present Paying constant attention to safety is always extremely important However, there are often situations that require special attention These situations are indicated throughout this book by the following symbols: DANGER DANGER – Immediate hazards which WILL result in severe personal injury or death Several important general precautions are listed below: DO NOT RUN EQUIPMENT DRY OR START THE PUMP WITHOUT THE PROPER PRIME (Casing Flooded) DO NOT EXCEED THE MAXIMUM DESIGN PRESSURE (MDP) AT THE TEMPERATURE SHOWN ON PUMP NAMEPLATE See Figure for general pressure versus temperature ratings of common alloys ALWAYS LOCK OUT POWER TO THE DRIVER BEFORE PERFORMING PUMP MAINTENANCE NEVER OPERATE THE PUMP WITHOUT COUPLING GUARD AND ALL OTHER SAFETY DEVICES CORRECTLY INSTALLED DO NOT APPLY HEAT TO DISASSEMBLE THE PUMP OR TO REMOVE THE IMPELLER Entrapped liquid could cause an explosion NEVER OPERATE THE PUMP FOR MORE THAN A SHORT INTERVAL WITH THE DISCHARGE VALVE CLOSED The length of the interval depends on several factors including the nature of the fluid pumped and its temperature This interval must be determined by the customer’s Engineering personnel NEVER OPERATE THE PUMP WITH THE SUCTION VALVE CLOSED WARNING WARNING – Hazards or unsafe practices which COULD result in severe personal injury or death CAUTION CAUTION – Hazards or unsafe practices which COULD result in minor personal injury or product or property damage EXCESSIVE PUMP NOISE OR VIBRATION may indicate a dangerous condition The pump must be shut down immediately DO NOT OPERATE THE PUMP FOR AN EXTENDED PERIOD BELOW THE RECOMMENDED MINIMUM FLOW (Figure 20) 10 THE PUMP SHAFT MUST TURN CLOCKWISE WHEN VIEWED FROM THE MOTOR END It is absolutely essential that the rotation of the motor be checked before installation of the coupling spacer and starting the pump Incorrect rotation of the pump for even a short period of time can unscrew the impeller, which can cause severe damage NOTE: ALWAYS COORDINATE

is designed to protect the pump during shipment and for dry, indoor storage for up to two months or less The procedure followed for this short term storage is summarized below: Standard Protection for Shipment : a Loose unmounted items, including, but not limited to, oilers, packing, coupling spacers, stilts, and mechanical seals are packaged in a water proof plastic bag and placed under the coupling guard Larger items are cartoned and metal banded to the baseplate For pumps not mounted on a baseplate, the bag and/or carton is placed inside the shipping carton All parts bags and cartons are identified with the Flowserve order number, the customer purchase order number, and the pump item number (if applicable) b Inner surfaces of the bearing housing, shaft (area through bearing housing), and bearings are coated with Cortec VCI-329 rust inhibitor, or equal Note: Bearing housings are not filled with oil prior to shipment c Regreasable bearings are packed with grease (Chevron SRI #2) d After a performance test, if required, the pump is tipped on the suction flange for drainage (some residual water may remain in the casing) Then, internal surfaces of ferrous casings, covers, flange faces, and the impeller surface are sprayed with Calgon Vestal Labs RP-743m, or equal Exposed shafts are taped with Polywrap e Flange faces are protected with plastic covers secured with plastic drive bolts 3/16 in (7.8 mm) steel, or 1/4 in (6.3 mm) wood covers with rubber gaskets, steel bolts, and nuts are available at extra cost f All assemblies are bolted to a wood skid which

Division Section 3.4 LONG TERM STORAGE LIFTING Long term storage is defined as more than two months, but less than 12 months The procedure Flowserve follows for long term storage of pumps is given below These procedures are in addition to the short term procedure The following describes how to lift pump components, assembled pumps, or pump, motor and baseplate assemblies Do not attempt to lift a pump mounted on a baseplate by itself Only a pump-motor assembly may be lifted once installed on a baseplate Solid wood skids are utilized Holes are drilled in the skid to accommodate the anchor bolt holes in the baseplate, or the casing and bearing housing feet holes on assemblies less baseplate Tackwrap sheeting is then placed on top of the skid and the pump assembly is placed on top of the Tackwrap Metal bolts with washers and rubber bushings are inserted through the skid, the Tackwrap, and the assembly from the bottom of the skid and are then secured with hex nuts When the nuts are “snugged” down to the top of the baseplate or casing and bearing housing feet, the rubber bushing is expanded, sealing the hole from the atmosphere Desiccant bags are placed on the Tackwrap The Tackwrap is drawn up around the assembly and hermetically (heat) sealed across the top The assembly is completely sealed from the atmosphere and the desiccant will absorb any entrapped moisture A solid wood box is then used to cover the assembly to provide protection from the elements and handling This packaging will provide protection up to twelve months without damage to mechanical seals, bearings, lip seals, etc due to humidity, salt laden air, dust, etc After unpacking, protection will be the responsibility of the user Addition of oil to the bearing housing will remove the inhibitor If units are to be idle for extended periods after addition of lubricants, inhibitor oils and greases should be used Every three months, the shaft should be rotated approximately 10 revolutions 3.4 LIFTING PUMPS AND PUMP ASSEMBLIES Lifting should only be done by trained personnel Pumps and motors often have integral lifting eyes or eye bolts These are intended for use in lifting the individual piece of equipment CAUTION Do not use eye bolts or cast-in lifting lugs to lift pump, motor, and baseplate assemblies Before lifting the equipment refer to the pump data sheet for the complete assembly weight Pump Components: Casing (#100): Use a choker hitch pulled tight around the discharge nozzle Rear cover (#106): Insert an eye hook in the drilled and tapped hole at the top of the cover Use either a sling or hook through the eye bolt Bearing housing (#119): Group I Insert a sling between the upper and lower support ribs between the housing barrel and the casing attachment flange Use a choker hitch when slinging Caution, make sure there are no sharp edges on the bottom side of the ribs which could cut the sling Group and Insert either a sling or hook through the lifting lug located on the top of the housing Power end: Same as bearing housing Bare Pump: Sling around the pump discharge nozzle, and around the outboard end of the bearing housing with separate slings Choker hitches must be used at both attachment points and pulled tight Make sure the completion of the choker hitch on the discharge nozzle is toward the coupling end of the pump shaft as shown in Figure The sling lengths should be adjusted to balance the load before attaching the lifting hook Pump, motor and baseplate assembly: If the baseplate has lifting holes cut in the sides at the end, (Type A Group 3, Type D, and Type E bases) insert lifting S hooks at the four corners and use slings or chains to connect to the lifting eye as shown in Figure Do not use slings through the lifting holes For other baseplates sling around the pump discharge nozzle, and around the outboard end of the motor frame using choker hitches pulled tight (Figure 6) The sling should be positioned so the weight is not carried through the motor fan housing Make sure the completion of the choker hitch on the discharge nozzle is toward the coupling end of the pump shaft as shown in Figure MK III PUMPS IOM - 11/8/02

installation, connection, operation and maintenance by skilled, qualified and responsible personnel ensures safe and proper use of motors Read instructions carefully before attempting to install, operate or service motors and retain for future reference and work with care Especially, safety precautions must be observed to protect personnel from possible injury which will be caused by high voltage, hot surface and rotating parts of 14 RECEIVING Check motor & nameplate data (HP, Pole, Voltage and etc.) Check any damage or loose parts during transportation and stop commissioning if necessary Turn shaft by hand to check smooth rotation If shaft is clamped by locking device to prevent axial movement of heavy rotor during transportation, please remove it to run motors and retain it for future transport CAUTION If the motor is supplied with eyebolts for lifting purposes, make certain that these tightened securely Use these for lifting the motor only Do not use these for lifting any equipment mounted to the motor Note that the direction of lift should not exceed 15 degrees form the shank of the eyebolt WARNING High voltage, hot surfaces and rotating parts of electrical machinery can cause serious or fatal personal injury and damage to property Qualified personnel should perform proper installation, operation and maintenance Recommendations to be familiarized are NEMA MG2, the National Electric Code, IEC364(prEN50110-1) and all sound local safety practices Before attempting maintenance or repair, avoid contact with energized circuits and disconnect and de-energize all power sources to the motor and to the necessary devices to avoid electrical shock Before motor is energized, avoid contact with rotating parts and ensure that shaft key is fully captive or removed When working near machinery with high noise levels, suitable protection must be used Automatic-reset thermal protection should not be used where unexpected automatic starting will be hazardous to personnel Proper safeguards or protective devices against possible failure of motor-mounted brake, especially on overhauling load applications should be provided and should not be by-passed And a suitable enclosure should be provided against access to the motor or other un-authorized personnel of 14 Grounding of motor against fatal injury to personnel should be in accordance with the National Electrical Code and applicable local practice Grounding cable and terminal should be securely crimped with proper crimping tools for safe grounding Repair of Explosion-proof motors should be made by Hyundai, U/L,CSA or other listed authorized service center to maintain those listings, safety and special feature in hazardous area The use of non-explosion-proof motors in hazardous area is prohibited unless they are expressly intended for such use STORAGE When storing motors without immediate installation, to keep motors in best condition, make sure of dry, clean, dust-free and low-vibration environment to avoid danger of bearing damage at rest Precautions should be taken to prevent the entrance of moisture, dust or dirt during storage especially for winding and bearing Before commissioning, make sure insulation resistance of winding In case of resistance values≤1㏁, the windings should be dried LOCATION Drip-proof motors (IEC protection degree ≤IP23) are intended for use in well ventilated areas where the atmosphere is reasonably free of dirt, moisture and corrosion and not intended for use in outdoor Enclosed motors (IEC protection degree ≥IP44) are intended for operation where they are exposed to dirt, moisture, dust and most outdoor conditions Explosion-proof motors are designed for operation in hazardous areas classified by Underwriters' Laboratories, National Electrical Code, Canadian Standard Association and IEC79 Chemical heavy duty enclosed motors are designed for use in highly corrosive or excessively moisture locations Standard ambient condition of motors are rated for ambient temperatures of -20℃∼ +40℃ (-40℃ with low temperature grease such as Beacon325) and altitudes below 1000m(3300feet) above sea level of 14 MOUNTING Mount motors securely on a firm and flat base and make sure of solid foot or flange solid foot or flange mounting All ball bearing normal thrust motors can be side wall or can be side wall or ceiling mounted and can be vertically mounted for motors up to and including 326frame(IEC200L) size For the recommendations of other applications, check nearest Hyundai office or sales agents Align motors accurately using flexible coupling for direct drive if possible Because the balance of motors is made by half-key, the coupling or pulley must be half-key balanced Mount or remove belt pulley or coupling only using appropriate means and cover them with a safety guard and avoid excessive belt tensions Consult drive or equipment manufacturer or Hyundai for drive recommendations The bolts for motor mounting and base assembly must be carefully tightened to prevent change in alignment and possible damage to the equipment applying the recommended tightening torques shown in table Use the recommended torques for medium carbon steel bolts identified by three radial lines at 120 degrees on the head and use 50% of the recommended torques for low carbon steel bolts with no ID marks In case of motors with holes in feet, these holes are used for the application of dual frame sizes Only holes are used for mounting in accordance with outline drawing Recommended Bolt Size Torque Inch Metric

operation of motors In case of belt pulley, ventilation opening of rim of pulley is essential for motors The ventilation must not be obstructed The distance between ventilation openings of motors and wall or obstacle should be maintained by minimum 25mm(1inch) and ventilation diameter divided by Motors with shaft ends pointing upward are to be provided with a cover by the customer to prevent foreign materials from falling into the ventilation or openings CAUTION In all cases, no surrounding structure should obstruct normal flow of ventilation air throught or over the motor of 14 POWER SUPPLY and CONNECTIONS Wiring of motor, control, grounding and overload protection should be in accordance with the National Electric Code and all sound local building codes or practices only by qualified technical personnel Power supply should agree with nameplate voltage and frequency and permissible variations of power supply are ±5% for frequency, ±10% for line voltage and ±10% for combined variation to avoid elevated temperatures and effects on the electromagnetic compatibility (IEC motors :±2% for frequency, ±5% for line voltage per IEC34-1, EN60034-1 for multi-voltage motors) Thermally-protected motors to prevent excessive temperature rise or overload have two terminals of protectors (P1,P2) and should be connected to the control panel according to the connection diagram inside of the conduit box CAUTION All explosion proof motors are equipped with thermostats These must be connected to the motor control in order to maintain the factory warranty , and for the install to comply with CSA, UL, NFPA, WCE, and other governing regulations Manual-reset protectors can be reset after motor cooled by pressing reset button and Automatic-reset protectors(no external button) reset automatically after motor cooled Do not use Automatic-reset protectors where unexpected automatic starting will be dangerous to personnel WARNING Do not use automatic reset protected motor where unexpected start could cause injury to operating personnel Dual voltage motors can be connected for the desired voltage using the connection diagram inside of the conduit box Minimum clearances between un-insulated live parts and between such parts and earth must not be below 8mm at Volts≤550V,10mm at Volts≤725V, 14mm at Volts≤1000V Because no presence of foreign objects, dirt or moisture is admitted in the conduit box, close unused cable entrance holes and the box itself in a dust- and watertight manner of 14 For motors with brakes, check satisfactory functioning of brake before commissioning Standard connection diagrams for three phase motors without any accessories are shown as below and rotation can be changed by interchanging any two line leads Use appropriate cable terminals with proper crimping tools and protective and permanent conductor connection without loose wire ends is important for safety (1) Leads, Single voltage (2) Leads, Dual voltage & voltage ratio

winding start with magnetic contactor, M2 contactor should be closed within two seconds after M1 contactor is closed * Part winding start at low voltage is satisfactory only for 4pole and above ( 4p, 6p, 8p and above ) OPERATION If the motor has been stored for an extensive period or in a damp location, check the insulation resistance of stator winding & bearings If the resistance of stator winding is lower than 1Mega Ω, dry out motors thoroughly with maximum drying temperature of 85℃ (185℉) in one of the following ways 1) Dry the stator in an oven until the insulation resistance is constant for a one-half hour period 2) Enclosure the motor with a canvas or similar covering leaving a opening at the top for moisture to escape Insert heaters or lamps with care to avoid localized damage due to too closer heating to the winding and leave them until the insulation resistance is constant for a one-half hour period 3) With the rotor locked, apply approximately 10% of rated voltage and increase current gradually through the windings until temperature measured with thermometer reaches 85℃(185℉; Do not exceed this limit) Maintain 85℃ until the insulation resistance is constant for a one-half hour period Turn the shaft by hand to check the bearing and it may be necessary to re-grease or 11 of 14 change rusted bearings depending on the period and condition of storage Operate motor at no load (disconnected load) and check rotation (without key if uncoupled) for free running Interchange any two leads to change direction of rotation for three phase motor Connect load and operate for an initial period of at least one hour to check any unusual noise, vibration or hot spots and check those items periodically even after successful start-up Acceptable vibration severities can be decided by NEMA MG1-7 (2∼6pole:0.15, 8pole:0.12in/sec peak) and IEC34-14 (H≤132:1.8,132＜H≤225:1.8 (4pole and larger) & 2.8(2pole), H≥225:2.8(4pole and larger) & 4.5(2pole) in mm/sec rms.) for no load and uncoupled condition Check operating current against nameplate current Be careful not to exceed the value of nameplate amperes multiplied by the service factor under continuous load When 208-230/460V motors with alternate voltage of 200V at 1.0 SF are used on 200V, the sip of motors will increase approximately 30% and torques will be reduced by approximately by 20 to 30% Therefore, user should check and determine that motors will start and accelerate without injurious heating and with adequate torque MAINTENANCE INSPECT motor regularly and keep motor clean and dry In case of heavy dirt or deposits, clean air channels periodically If the period of storage or stop of running of motor is more than one month, turn the shaft by hand to check the smooth rotation of bearings every one month and check the insulation resistance of winding every three months as minimum Special features of Explosion-proof motors should be maintained in accordance with U/L, CSA or other authorized standard in hazardous area Therefore, repair of Explosion-proof motors is recommended to be made by Hyundai, U/L, CSA or other listed authorized service centers to maintain those listings, safety and special features In order to clean stator windings, use a soft brush and a slow acting solvent (if necessary) without affecting on coils, insulation and varnish in a well ventilated room for safety 12 of 14 LUBRICATION for maintenance Double shield and pre-lubricated ball bearing motors without grease fittings are adequately greased for life at the factory and not need re-lubrication Motors with re-greasing facilities are shipped with grease for initial running and should be checked and re-lubricated periodically depending on the type of service (see below table) to maintain maximum bearing life Do not lubricate excessively or too frequently to avoid damage of bearing and leakage of grease Conditions Standard Severe Very Severe Operation per day 8hrs, 1or 2shifts 24hrs,
